That Guy Can't be Killed (あいつは殺せない, Aitsu wa Korosenai) is chapter 322 of the Naruto manga.
Asuma admits that he hasn't smoked recently, but insists it is not because of worry over a fight with Akatsuki, although he is concerned about how they will fare. In Konoha, Naruto and his shadow clones struggle to combine wind release with the Rasengan, a process that is frustrating enough that some clones lose control of the demon fox's chakra. Yamato suppresses them. Elsewhere, Hidan waits outside a bounty station for Kakuzu to finish his business. Asuma appears and attacks him, though Hidan blocks the attack. Before he can retaliate he is captured by Shikamaru's shadow, giving Izumo and Kotetsu a chance to strike. They believe they have killed him, but Hidan merely asks who they are.
